Cairo "Could not find libpng in the pkg-config search path"

Question

I'm trying to install GTK-DFB and cairo is a requirement. When I try to build it from source, it throws:

checking for cairo's PNG functions feature... 
configure: WARNING: Could not find libpng in the pkg-config search path
checking whether cairo's PNG functions feature could be enabled... no
configure: error: recommended PNG functions feature could not be enabled

Ideas?

Thanks

Answer 1

You need to have the libpng development packages installed; Installation is distribution dependent, but for debian derivatives following should be enough:

apt-get install libpng12-dev

Purim

I think on fedora, the package is called libpng-devel – Purim

Answer 2

For me it helped to export the following variable in the shell:

export png_REQUIRES="libpng"

I had to do export png_REQUIRES="libpng16" – Brilliance

This worked for me. png_REQUIRES="libpng" ./configure – Camelopardalis

If you're on Ubuntu, another much faster solution is to do:

apt-get build-dep gtk+2.0
